HECTOR HENRY GARRATT, OF SME'IHWICK, ENGLAND, ASSIGNOR TO HENRY HOPE & SONS LIMITED, OF SMETHWICK, ENGLAND.

CASEMENT FASTENER.

Application filed July 16, 1926, Serial No. 122,981, and in Great Britain September 7, 1925.

This invention relates to fastenings for vertically pivoted and side-hung easements, and has for its object to provide an improved stop device for limiting the angle through which the handle can be freely moved.

The invention comprises the provision of a stop or stops as an integral portion of the profile of the handle plate, thereby dispensing with the projecting lugs, studsor pins ordinarily employed, such plate being provided with a pivot for the handle and the latter with a fixed spur or projection on its rear side, which, in association with the stop or stops aforesaid limits the handle movement.

In the accompanying drawings Figures 1 and 2 are side and front elevations illustrating one application of the invention.

In carrying the invention into effect, as

shown, a casement handle a is pivoted on the handle plate I) attached to the window member c. The profile of the handle plate is such that it provides a pair ofstops e, f for engagement by a spur or projection g at the rear of the handle. Preferably the plate is formed with a symmetrical profile as shown in order that its attachment to the window bar a can be made with either half of its profiled edge upwards.

It will be understood that the'stop 6 serves to limit the extent to which the handle can be moved into the engagement with the fixed window frame and the stop f serves to limit the reverse movement. The stop f can, if

desired, be omitted so that limitation of the V a pivot on said plate,.a handle carried on the pivot, two pairs of symmetrically arranged complementary stops inte ral with the peripheral portion of the handle plate, and a projection on the handle adapted to co-operate with either pair of stops for limiting the handle movement, substantially as described, the pairs of symmetrically arranged'complementary stops permittingthe handle plate being attached inreversed positions.

In testimony whereof I have signed my name to this specification.

HECTOR HENRY GARRATT.
